When you take a screenshot you will likely be referring back to it within some context of some sort.. this is the end-use for the screenshot.
Again preference wins here then, if you have lots of options at the point of taking the shot, then, you have access to preferences that will aid you in your later use of the screenshot, so..
Not only does the screenshot taken with @evernote Web Clipper get added to the Cloud " instantly " for you to tend to later.. but you get a multitude of options while taking the screenshot -- It's like Pocket built into @evernote for clipping any webpage.
At this point there is no option more robust than @evernote if you plan to actually use the screenshot later within some context, @evernote, gives you lots of options while taking the shot, and, after the shot has been captured for how you want to later manage that shot.
Unless you're a designer and you're building a mood-board, I highly suggest Evernote's Web Clipper tool, it has been around for a while and has been improved immensely over time.
